Facebook cellphone tease campaign from UK carrier Three

UK carrier Three have begun a teaser campaign for what they're calling a "revolution" in mobile Facebook access.  Set to be announced on November 13th, Three believe the new handset "will change the way you use Facebook on your phone"; however they give no other details.

It's unclear what differences a specific Facebook handset could bring, compared to the existing mobile access version of the social network's website or the special software that's on offer for certain devices (such as the iPhone).   

Assuming this is a direct collaboration with Facebook, it's not the first time that Three have worked with a company to produce a customized cellphone.  The carrier already sells a 3G Skype handset, with inclusive use of the data network to make VoIP calls at lower rates than traditional mobile calls.
